A method for cleaning a turboshaft engine blade comprising a superalloy body covered with a coating, in which the coating of the blade is at least partially machined using a pulsed laser. At least the feed rate of the pulsed laser and the pulse frequency of the pulsed laser are parameterized such that the machined surface of the blade has a roughness of 4 μm to 10 μm.
